This invention relates to control mechanism for full fashion textile machines whereby the length of hosiery can be accurately regulated and hasforits primary object the design and corelation of mechanismswhere-.

by the control rod of the textile machine may be automatically manipulated directly from a movable part of the machine according to the number of the rotations of the take-up shaft.

Another object the provision of mechanism whereby the numberrof turns made by a take-up shaft in the winding of the hosiery willautomatically.

mechanism can be manually regulated.

the design of and the operation of automatic mechanism directly off the take-up shaft for periodic manipulation of the control rod of the machine whereby the machine is perlodically stopped and started.

A feature of the invention resides in the direct relation of the control rod with the control mechanism whereby the latter may be automatically reset in the manipulation of the control rod manually.

Another feature of the invention resides in the novel construction, design and-association' of the various parts of the various mechanisms whereby the mechanisms may be periodically thrown into operative connection with the movable part of the machine for the manipulation of the control rod accordin to the length of the hosiery desired.

My invention is also distinguished in a design of mechanism that is directly controlled bythe length of the hosiery as the same is manufacturedthereby assuring accurate length of all portions of the hosiery.

.Vith these and other objects in view the invention will be better understood from the of the invention resides in I the release mechanism which. controls the operation of themanipulating Another object of this invention resides in following detailed description taken in con-, nection with the accompanyingdrawings f whereinv v a 1 Figurel isLafront elevation of the invention. a t Figure 2 is a side elevation. 1 Figure 3 isa detailed elevation of a por-e tionof the mechanism.

V y Again referring to the drawings illustrate ing oneof the many constructions of my invention, '1 designates one of the power shafts or cam shafts of a full fashion textile machine to which is'directly connected a cam 2.

The takej-upshaft id of the textile machine is arranged contiguous to the controlrod 4 so. that my improved mechanism may have a' direct operative relation with the shaft 3 and the control rod 4.- V

7 My invention consistsbasically of manipulating mechanism, release mechanism, tripping mechanism and setting mechanism, all ofwhich are so corelated that the manipulating mechanism is periodically moved into 7 operativeengagement withcam 2 by the re lease mechanism, the latter in turn depending for its operation upon release of the trip mechanism that; is under direct control of the take-up shaft 3. I a

. The setting mechanism is so designed that in the manual manipulation of the control rod-4:, the releasing mechanism willbe auto-- matically reset.

' Manipulating mechanism The manipulating mechanism consists of aQme'mber or slide 9 mountedin guide bearings l0 and carrying a roller 11 directly re lated with thec'am 2. .As this slide 9has I a pivotal'connection 12, with the connecting I rod 13 it will be appreciated that the slide 9 may be swung laterally to move the same into and out of the path of travel of the main purpose ofv mounting cam 2. The connecting rod 13 has a pivotal connect-ion 14 with one arm of a bell crank 15 that is connected to the control rod 4 sothat upon movements of the rod 13 the control rod 4 will be manipulated through the bell crank 15.

Release mechanism The release mechanism consists of a bell crank lever 16 having a direct connection with the slide block 17 that is provided with the groove, 18, the walls of which form bearings for one limb of the arm 9. The bell crank lever 16 has a pivotal connection19 with a link 20 which in turn is connected to a second bell crank lever 21""carried by a bracket 22.' This bell crank lever 21 is constantly urged in a downwardly direction by a spring 21?) attached thereto and having its other end secured to the bracket 22. This spring is utilized to urge link 20 downward- 1y when released-as hereafter set forth.

Tripping mechanism The tripping mechanism consists of a catch 23 fixed to the bell crank lever 21 by a pin member 236 so as to turn with the bell crank lever. This catch is of a crescent shape formation to cooperatewith the pin member 23b to define a recess 230 for accommodating passage of associated parts under. conditions herein set forth and further to provide proper locking engagement with trigger 24. The trip device consisting of the catch23 and trigger 24 is arranged to be releasedby a plurality of tappets 25 adjustable on a rack bar 26 slidably mounted in a guideway 26?) formed in the bracket 22 and this rack bar is geared to the take up shaft 3 by the gear wheel 27. This rack bar 26 is provided with a track receiving the heads 28'of the tappets. The heads 28 are connected to dogs 29 designed and associated with the'heads to swing in one direction only so that in the upward movement of the tappets the trigger 24 will be disengaged from the catch23 whereas in the return movement of'the tappets the dog 29' will slide over the trip device thereby preventing manipulation thereof. The rack bar is manually returned to its normal position by the turning of shaft 3 in theiunwinding of the stocking leg blanks therefrom.

Each head 28 of the tappets" 25 is provided witha set screw 30 by-means of which the tappet may be fixed in any desired adjusted position along the rack bar 26. The such tappet in adjustablerelation to the rack bar is'to selectively control the stopping of the machine finished stocking. To complete the. invention, a link 31is pivotally connected to the bell crank 15 and provided with a slot 326 associated with a pin 32 carried by the bell for varying the shape or construction of the crank 21 for providing a loose connection between the bell crank 21 and link 31.

In the diagrammatic view, Figure 7 I have designated by the numerals 1 to 6, the various stages in the construction of the hosiery blank where the machine will be automatically stopped by my control mechanism. It is, of course, to be understood that the distance between each stop and the number of stops may be varied at will by changing the number of and relation of the tappets. The relative arrangement of the pin 32 and walls of the slot 326 is a very important feature of my invention as this accommodates proper resetting of the mechanism when the control rod 40 is manually manipulated. In other words, the pin 32 is positioned in the slot 325 and the length of the slot is of a de gree that when the machine has been stopped automatically by the turning of the control rod '4 by the connecting rod 13, the link 31 will slide free of the crank lever 21 but upon manual turning of the control rod 4 in the reverse direction to start the machine the engagement of the pin with an end portion of the slot will cause movement of the bell crank 21 and the resetting of the device to be automatically operated at another predetermined point in the operation of a textile machine.

In the operation of the invention the various tappets are set accurately along the rack bar so as to periodically and successively engage an-d trip the trigger-24 for allowing the bell'crank 21 to turn about its pivot and slide the link 20. Movement of the link 20 manipulates the slide block 17 which in turn moves the roller .11 into operative relation with the cam 2; In the rotation of the power shaft 1, the cam 2 will move the slide 9 vertically, the slide in turn moving the connecting rod 13 for giving a partial turn to the bell crank 15. As the bell crank 15 is fixed to the control rod 4, it will be understood that the control rod is turned the stop the textile machine. Due to the pin and slot connection 32 between the link 31 and the bell crank 21, full movement of the control rod 4 to a position to start the machine will movethe bell crank 15 the required degree to reset the trigger 24 into engagement with the catch 23 for repeating the operation of the mechanism." In other words, the relation of the pin 32 and walls of the slot 326 are suchthat the cam 2 is capable of moving upwardly the connecting rod 13 and through it the bell crank 15 to turn the control rod 4 and automatically stop the machine. l/Vhen required degree to this is taking place the link 31 rides freely of the bell crank 21 thereby not interfering in any way whatsoever with the operative relation of the roller 17 with the cam 2. This movement of the link 31 to a predetermined extent brings into proper cooperative rela-' in the opposite direction to start the textile machine engagement between an end wall of the slot 32?) and the pin 32 will cause the bell crank 21 to turn in the proper direction to elevate link 20 and through the bell crank 16 bring the roller 17 out of operative relation with the cam 2 so that the entire mechanism will be reset for another cycle of operation at the proper time, that is to say, when a dog 25 comes into proper engagement w1th the trigger 24. i

Attention is called to. the fact that my mechanismautomatically moves the control rod in a direction to stop the machine and the control rod in its movement automatically resets my control mechanism for passage through another cycle of operation when re leased by another tappet. As the gear 27 is fixed to the take up shaft of the textile machineand the take up shaft is directly connected to thestocking being formed and fur-.

ther the gearhas a fixed connection with the rack bar, it. will be understood that movementof the rack bar is in accuraterelation to the length of the stocking being formed and therefore accurate engagement of each tappet with the trip device in accordance with the length'of the hosiery as being manufactured.

In the removing of the stocking as mounted around the take up shaft 3, the rack bar is automatically moved towards its normal position, the dogs 25 passing freely by the trip device due to their pivotal connection with the heads of the tappets. I

In concluding, I wish to stress the fact that I am of the opinion that I am the first to interpose automatic control mechanism between the power shaft and ,the control shaft of a full fashion textile machine, and further interpose control mechanism between the power shaft, control rod and the hosiery take up shaft, whereby in the wrapping of the hosiery as manufactured, the take up shaft will automatically control the operation of the manipulating mechanism from the power shaft for automatically operating the control rod to stop the textile machine.

I am of the opinion, that I am the first to arrange automatic control mechanism to take its power directly off the textile machine in accordance to the extent of travel of the take up shaft of the textile machine. Therefore, I am entitled to broad protection for thenew combination set forth irrespective of the construction of component'parts which may be modifiedmany ways without departing from the spirit of my invention and therefore I do not desire to be limitedin protection in any manner whatsoever exceptas set forth in the following claims. 7 i
